Richard Sandiford <rsandifo at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |FIXED Status|ASSIGNED |RESOLVED --- Comment #15 from Richard Sandiford <rsandifo at gcc dot gnu.org> --- I didn't manage to reproduce the PR in the originally reported form, but FWIW, the patches mean that a gcc_unreachable above: return decl; in simulate_builtin_function_decl no longer fires for arm_sve.h or arm_sme.h. Please reopen if there are still some lingering issues.
